Previous research has confirmed that the distribution of bids for construction auctions can be reasonably modeled with Lognormal distribution. The location parameter this (the mean μ) been found to have a good linear correlation bidders’ cost estimates. However, scale (standard deviation bids, σ) remains noticeably difficult anticipate. By analyzing 13 auction datasets, hard evidence is provide...

Sentences are important semantic units of natural language. A generic, distributional representation of sentences that can capture the latent semantics is beneficial to multiple downstream applications. We observe a simple geometry of sentences – the word representations of a given sentence (on average 10.23 words in all SemEval datasets with a standard deviation 4.84) roughly lie in a low-rank...

Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This series in Advances in Physiology Education provides an opportunity to do just that: we will investigate basic concepts in statistics using the free software package R. Because this series uses R solely as a vehicle with which to explore basic concepts in statistics, ...
